Ultra reliable and low latency communications (URLLC) is a new service category in 5G to accommodate emerging services and applications having stringent latency and reliability requirements. In order to support URLLC, there should be both evolutionary and revolutionary changes in the air interface. In this talk, I will provide an up-to-date overview of URLLC with an emphasis on physical layer challenges and solutions. I will also introduce new transmission technique called sparse vector coding.
Byonghyo Shim received the B.S. and M.S. degree in Electrical Engineering from Seoul National University (SNU), in 1995 and 1997, and the M.S. degree in Mathematics and the Ph.D. degree in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign (UIUC), Urbana, in 2004 and 2005. He industry experiences include LG Electronics, Texas Instruments, and Qualcomm. Since September 2014, he has been with the Dept. of Electrical and Computer Engineering, SNU, as a professor. Dr. Shim was the recipient of the M. E. Van Valkenburg Research Award from University of Illinois, Qualstar Award from Qualcomm CDMA Technology, Hadong Young Engineer Award from IEIE, and Irwin Jacobs Award from Qualcomm and KICS. He has been served as an associate editor of IEEE TSP, IEEE WCL, Journal of Communications and Networks (JCN), and a guest editor of IEEE JSAC.
